 Guidelines for Participating

Here are a couple of guideline for participating in these events:

  1. Helmets should always be protecting your head at ALL times when on your bike (before, during and after your event)
  2. Please give everyone the same experience that you would want, meaning the course closes at the start time for a category, and NO ONE else should be on course
  3. Consider the safety of yourself and others, HEADPHONES of any sort are not allowed
  4. Common courtesy allows someone to pass when asked
  5. Proper language is very much appreciated

These just help make it safe and fun for all participants.

  • Once you have registered and start riding the course, you are part of the event, NO refunds will be issued once you start the event.
  • If you have pre-registered and need to request a transfer please send an email to Hello@BellLapProductions.com at least 24 hours before the start of the event.

Bell Lap Production, LLC reserves the right to cancel an event due to issues beyond their control, such as something weather related. Bell Lap Production, LLC will do what they can to accommodate each person who has pre-registered by allowing a transfer to another event, when appropriate.

Start Time



  Rory will be directing participants to start in their appropriate Category Time as noted above, and then by their division (ie 50+, or 40-49 to name a few). Everyone should be started within around 6 minutes of the first rider off. Please listen to directions for starting.

Please remember that courses are tentative and may be adjusted on race morning. The lap count is a courtesy, not a guarantee. Course conditions can impact this on either side of the time frame.

After the first finisher in the time slot crosses the finish line, everyone will be finished as they cross. Participants will be scored based on how many laps completed and then their finish time.

Here is the tentative course, same as 2021, but COUNTER CLOCKWISE:

 Series Information

Points are awarded to each finisher in each division and category at the completion of each event and are carried over to the next event. The final event will be a stand alone event and will not count towards series points. At the final event we will have the series ending podium ceremony. This way, people can review the results and let BuDu Racing, LLC know ahead of time if there is an issue that needs to be reviewed.

In order to be eligible for season ending prizes, you must participate in 5 of the 8 events. The last event is a stand alone race, with prizes of its own. This will help the series ending awards go more smoothly. If you participate in all 7 events (in the points series), you will receive a series bonus of 15 points. Your accumulative series points will be a composite of your top five event finishes plus the series bonus (as applicable). Each participant who starts an event will automatically receive one point. If you want to change categories, you can, but you will need to remain in that category for the rest of the series (you can not return to the previous category). We have adjusted the series points to stay the same when transferring, as the lower category events have less points. You may not place in the series in more than one category. Ties will be determined by the person who has placed the highest when competing at the same event.

Series ending awards will be presented at the final event. If you are not present to accept your award, it will be your responsibility to make arrangements to receive your award.

We will be taking $1 from each registration and adding that to a pool for the series ending payout the bigger the numbers, the bigger the payout. The promoter reserves the right to change categories, places, and prize list based on participation. While this is not a USCF/NORBA event, rules will be enforced. This includes wearing a HELMET at ALL times when on your bike.


 Mandatory Upgrade

It is our hope that participants who are exceeding in their field will choose to Upgrade during the season, as accrued points will move up to the higher category. Should we notice a participant, who is more than 8 minutes ahead of the second-place person, at 2 or more events, we will require the person to Upgrade to the next Category (unless there is an extenuating circumstance communicated to us). The only exception to this is the Cat 1 field, which is the top already. However, if a Cat 1 age group person is exceeding to the extent listed above, we will do the same for that person moving the person to the Cat 1 OPEN division. This will encourage riders to compete in Categories/Divisions where they are challenged and can truly improve their riding and competition skills. As always, points will transfer up to the category, so there is not a loss of points.

 Lapped Riders

If a participant is lapped by the lead rider, you will finish on the same lap as the leader. On the final results it will indicate how many laps you completed. 

 Transfers to a Different Category

Transfers to a different category, which means you are moving up a category, are allowed with points transferring, but must take place before the 6th race. No transfers with points will be allowed after the 5th event. After transferring, in order to be in contention to win a Series Placing, you must have competed in at least 3 of the category events you are placing in. 

If you transfer down a category or lateral within a category, your points will NOT transfer.

You can request to be transferred to a category by emailing Help@BellLapProductions.com or talking with one of the registration staff members.

 Individual Event Awards

We will be awarding medals for First, Second, and Third finishes in each category and division (as appropriate).
